NASA will try to launch Artemis again on Saturday, Sept. 3



NASA will make its second attempt at launching its 'mega moon rocket' this Saturday (Sept. 3.), the space agency announced, just days after scrubbing the rocket's first liftoff attempt following an engine issue.

The Artemis 1 rocket is made up of the six-person Orion capsule perched atop the 30-story Space Launch System (SLS) — dubbed the 'mega moon rocket' — and was initially scheduled to embark on its maiden voyage to the moon and back on Monday (Aug. 29). But engineers were unable to cool one of the rocket's four core stage RS-25 engines down to a safe temperature in time for launch. That issue, along with poor weather conditions, forced NASA to cancel the launch just two minutes into the spacecraft's two-hour launch window, NASA officials said at a news conference on Tuesday (Aug. 30).

The rocket's new window for a second attempt will be on Sept 3., one day later than the earliest available window of Friday (Sept. 2.), which NASA ruled out due to a high risk of adverse weather conditions.

"The launch pad time for a Saturday attempt would be 2:17 p.m. EDT," Mike Sarafin, NASA's Artemis mission manager, said at a news conference on Tuesday. "It's a two-hour window." NASA officials added that if the rocket didn't take off on Saturday, another launch could be scheduled as soon as 48 hours later.

NASA views this flight as the first of three missions that will be a vital testbed for the hardware, software and ground systems that are intended to one day transport the first humans to Mars and beyond. The upcoming uncrewed Artemis 1 test flight — part of the Artemis program named after the twin sister of the ancient Greek god Apollo — will be followed by Artemis 2 and Artemis 3 in 2024 and 2025/2026 respectively. Artemis 2 will make the same journey as Artemis 1, but with a four-person human crew, and Artemis 3 will send the first woman and the first person of color to land on the moon's south pole.

Monday's launch was scheduled for 8:33 a.m. ET, but the attempt was plagued with problems from the beginning. Initial fueling attempts hit delays in the early hours of Monday morning when lightning, which had already struck the Artemis rocket pad two days before, threatened to zap the rocket again.

Then, not long after 3 a.m. ET, the launch team announced it was having problems filling the rocket with supercooled liquid hydrogen fuel. These problems are reminiscent of those the team reported having during April's wet dress rehearsal, where a faulty helium valve and a liquid hydrogen leak prevented the rocket from being prepared to the point of ignition, Live Science previously reported. Another snag for Monday’s failed launch came when engineers spotted a suspected crack in the rocket's thermal insulation, although it was later deemed to be superficial.

The issue that finally scuppered the launch arrived just after 6 a.m. ET, when the team declared that the liquid hydrogen fuel was only cooling three of the rocket's four engines to sufficient temperatures prior to ignition. The problematic engine, named engine three, appeared to be around 40 degrees Fahrenheit (22 degrees Celsius) warmer than the temperature of minus 420 F (minus 250 C) needed for launch.

NASA will attempt to fix this issue for Saturday afternoon's launch by performing the engine chilling procedure half an hour earlier — a trick officials say was effective during a successful test conducted last year.

And the engine may not have trouble cooling at all; NASA scientists have suggested a faulty temperature sensor may have falsely reported the temperature inside the engine as being much higher, and much further from flight-ready, than it actually was.

"The way the sensor is behaving does not line up with the physics of the situation," John Honeycutt, NASA's program manager for the Artemis 1 mission, said at the news conference.

The faulty sensor cannot be easily replaced, and swapping it out would likely mean the rocket has to be rolled back to NASA's Vehicle Assembly Building for a thorough investigation. As this would probably mean delaying the launch for several months, Honeycutt said that his team was looking into creating a workaround plan that would enable flight engineers to make an "informed decision" on whether the rocket could take off without taking readings from the sensor.

NASA is banking heavily on a successful mission for Artemis 1, which has come under scrutiny for a price-tag that has ballooned to eye-watering levels. The program, which began in 2017, has already cost more than $40 billion to develop and is projected to knock U.S. taxpayers back by $93 billion by the end of 2025, according to the office of NASA inspector general Paul Martin — the space agency's internal auditor.

"Given our estimate of a $4.1 billion per-launch cost of the SLS/Orion system for at least the first four Artemis missions, NASA must accelerate its efforts to identify ways to make its Artemis-related programs more affordable," Martin said at a March 1 testimony before the House Subcommittee on Space and Aeronautics. "Otherwise, relying on such an expensive single-use, heavy-lift rocket system will, in our judgment, inhibit if not derail NASA's ability to sustain its long-term human exploration goals of the moon and Mars."

Despite these issues, NASA officials insist that the American public will find the cost of the rocket — which they say will kickstart a new era of space exploration — to be justified.

"This is a brand new rocket. It's not going to fly until it's ready," NASA administrator Bill Nelson told reporters on Monday following the scrubbed launch. "There are millions of components of this rocket and its systems, and needless to say, the complexity is daunting when you bring it all into the focus of a countdown."

Nelson added that his own space shuttle launch, held in 1986 while he was a member of Congress, had four scrubs before it eventually took off.

"Had we launched on any one of those scrubs, it wouldn't have been a good day," he said.

NASA will be eager to launch Artemis before Sep. 10, the peak date of this year's hurricane season. So far, no named hurricanes have formed this year, but signs of increasing storm activity in the Atlantic basin suggest the period of unusual calm could be about to end.

The August 2022 jobs report has been released. 315,000 jobs were added.

That brings the total since President Biden took office to nearly 10 million jobs. That's the fastest job growth in our history.


Payrolls rose 315,000 in August as companies keep hiring

Nonfarm payrolls rose by 315,000 jobs in August, just below the Dow Jones estimate for 318,000.

Wages also rose, with average hourly earnings up 5.2% from a year ago.

The biggest sector gainers were professional and business services, health care and retail.

Webb telescope captures its first image of exoplanet



The James Webb space telescope has taken its first image of an exoplanet -- a planet outside our solar system -- as astronomers hail the device's performance since its launch last year.

Images from the most powerful space telescope ever built have thrilled observers in recent months as it orbits the Sun a million miles (1.6 million kilometers) from Earth.

Its latest pioneering pictures show the exoplanet, called HIP 65426 b, is a gas giant with no rocky surface and could not be habitable.

"This is a transformative moment, not only for Webb but also for astronomy generally," said Sasha Hinkley, astronomy professor at the University of Exeter, who led the observation team.

Webb's infrared gaze and coronagraphs -- telescopic attachments that block out starlight -- enable it to take direct images of exoplanets.

"It was really impressive how well the Webb coronagraphs worked to suppress the light of the host star," Hinkley said in a NASA statement on Thursday.

The HIP 65426 b exoplanet is six to 12 times the mass of Jupiter and young -- about 15 to 20 million years old, compared to the 4.5-billion-year-old Earth.

The telescope, which only released its first images in July, has already revealed dazzling new detail of the Phantom Galaxy and of the planet Jupiter.

The Hubble space telescope previously captured direct exoplanet images, but in far less detail.

"I think what's most exciting is that we've only just begun," said Aarynn Carter, of the University of California. "We may even discover previously unknown planets."

The $10-billion Webb telescope is a collaboration between NASA, the European Space Agency and the Canadian Space Agency. It is expected to operate for approximately 20 years.

Launch attempt of Artemis 1 scrubbed after leak detected; next try will come in October

NASA Administrator Bill Nelson, Associate Administrator for Exploration Systems Development Jim Free and Artemis Mission Manager Mike Sarafin spoke Saturday around 4 p.m., addressing the scrub of Saturday's Artemis 1 launch.

"We do not launch until we think it's right," Nelson said. "Our teams have labored over that and that is the conclusion they came to...Safety is the top of the list."

Free said the launch will not come Monday or Tuesday, but will need to be later, likely late September or October. Late September is less likely because of conflicts with SpaceX Crew 5.

"We don't go into these tests lightly," Free said. "We were confident coming into today, but we're not going to launch until we're ready."

Sarafin stated the large hydrogen leak occurred when crews went from the "slow fill" to the "quick fill."

He said teams tried three times to resolve the leak, but were unsuccessful.

Sarafin said engineers discussed multiple options but none would have allowed for the launch to take place before the end of the launch period on Sept. 6.

Officials confirmed the rocket will need to be rolled back to VAB because batteries need to be changed.

Pakistan flood toll rises with 25 children among 57 more deaths



KARACHI, Pakistan (Reuters) - The toll from cataclysmic floods in Pakistan continued to climb on Saturday with 57 more deaths, 25 of them children, as the country grapples with a relief and rescue operation of near unprecedented scale.

A high-level body set up to coordinate the relief effort met in Islamabad on Saturday for the first time, chaired by Prime Minister Shehbaz Sharif, to take stock of the disaster.

Record monsoon rains and melting glaciers in northern mountains brought floods that have affected 33 million people and killed at least 1,265 people, including 441 children. The inundation, blamed on climate change, is still spreading.

The proportion of children's deaths has raised concern. On Friday, the United Nations children's agency (UNICEF) said there was a risk of "many more" child deaths from disease after floods.

The floods that have inundated a third of the country were preceded by four heatwaves and multiple raging forest fires, the disaster management chief told the high-level meeting, highlighting the effects of climate change in the South Asian nation.

"The year 2022 brought some harsh realities of climate change for Pakistan," the chief of the National Disaster Management Authority Lieutenant-General Akhtar Nawaz told a briefing for the country's top leadership.

"This year we did not witness a spring season - we faced four heatwaves which caused large-scale forest fires across the country," he said.

The fires were particularly severe in the southwestern province of Balochistan, destroying swaths of pine-nut forests and other vegetation, not far from areas now underwater.

Balochistan has received 436% more rain than the 30-year average this monsoon.

The province has seen widespread devastation, including a washing away of key rail and road networks as well as breakdowns in telecommunications and power infrastructure, the meeting was told.

The country has received nearly 190% more rain than the 30-year average in the quarter through August, totalling 390.7 millimetres (15.38 inches). Sindh province, with a population of 50 million, was hardest hit, getting 464% more rain than the 30-year average.

Aid has flowed in from a number of countries, with the first humanitarian assistance flight from France landing on Saturday morning in Islamabad. But Pakistan's largest charity group has said there were still millions who had not been reached by aid and relief efforts.

Initial estimates of the damage have been put at $10 billion, but surveys are still being conducted along with international organisations.

The United Nations has appealed for $160 million in aid to help tackle what it said was an "unprecedented climate catastrophe" as Pakistan's navy has fanned out inland to carry out relief operations in areas that resemble a sea.

Dinosaur fossil from asteroid strike that caused extinction found, scientists claim - BBC News

A dinosaur's leg, stunningly preserved, has been presented by scientists claiming it was likely killed by a giant asteroid which caused the species' extinction.

The limb, complete with skin, is just one of a series of remarkable finds emerging from the Tanis fossil site in the US State of North Dakota.

But it's not just their exquisite condition that's turning heads - it's what these ancient specimens purport to represent.

The claim is the Tanis creatures were killed on the actual day the asteroid struck Earth 66 million years ago, which saw the reign of dinosaurs end.

The BBC's Rebecca Morrelle reports.

Yankees' Aaron Judge homers for third consecutive game, raises season total to 54

The Yankees star is now just seven homers shy of matching Roger Maris' AL record



New York Yankees slugger Aaron Judge hit his majors-leading 54th home run of the season on Monday against the Minnesota Twins, pulling him to within seven home runs of matching Roger Maris' franchise and American League single-season record of 61, established back during the 1961 season. Judge reached a new personal best on Sunday after he launched No. 53 in a victory against the Tampa Bay Rays.

Judge's Monday home run, a two-run shot and his third in as many games, came in the bottom of the sixth inning against right-handed reliever Trevor Megill. The home run broke up what had been a 2-2 tie between the teams. Here's a look at the blast in all its moving picture glory:

Watch: https://twitter.com/i/status/1566864560824500225

According to Statcast, Judge's home run left his bat with a 109.6-mph exit velocity and carried 404 feet.

The Yankees will have 27 games remaining on their schedule after Monday. If Judge continues to hit home runs at his current pace -- a home run every 2.5 team games -- he would finish the season with 65 on the year. That would, of course, shatter Maris' records for the franchise and the AL alike. It would also tie Judge for the fourth-most in a single-season all-time, and it would leave him trailing only seasons from Barry Bonds (73 in 2001), Mark McGwire (70 in in 1998), and Sammy Sosa (66 in 1998).

It's worth remembering that Judge is an impending free agent. He rejected the Yankees' seven-year extension offer in spring training that would have paid him $213.5 million. CBS Sports recently projected him to serve as the top free agent in the upcoming class, noting that only one other player (Paul Goldschmidt) had accumulated more Wins Above Replacement during the Pandemic Era.

Liz Truss wins race to be next U.K. leader and succeed scandal-hit Boris Johnson

Truss, who beat former finance minister Rishi Sunak to be elected the leader of the ruling Conservative Party, inherits a country facing a dire winter energy crisis, widespread strikes and economic recession



LONDON — Liz Truss will be Britain’s next prime minister after she was elected leader of the ruling Conservative Party on Monday, ending a race to succeed the scandal-tarnished Boris Johnson.

Truss, 47, has been foreign secretary and was the clear front-runner. She clinched victory by appealing to the right-wing party faithful as a tax-cutting, anti-"woke" candidate who would take a hard line on post-Brexit dealings with the European Union.

She inherits a country facing a dire winter energy crisis, widespread strikes and economic recession — as well as long-term questions about the erosion of its cherished public services and its status as a world power after Brexit. Those issues were largely absent from discussion in the two-month leadership race, in which she defeated the former chancellor of the exchequer, or finance minister, Rishi Sunak, by 57% to 43% in the final runoff.

That is a smaller margin than opinion polling had suggested and than her supporters may have hoped for.

As leader of the country's largest party, she will be appointed prime minister by Queen Elizabeth II at Balmoral Castle in Scotland on Tuesday, a break from tradition for the aging monarch, who has always performed the royal duty in London.

Truss, addressing a crowd of Conservative activists and lawmakers at an announcement event in the capital, joked that the lengthy leadership race was "one of the longest job interviews in history."

Her victory means she will become the country’s third female leader, after Margaret Thatcher and Theresa May.

Johnson announced his resignation in July when six months of rolling scandals culminated in a critical mass of his own lawmakers’ abandoning him.

Most of Britain’s 67 million people had no say in Truss’ ascension. Instead, she was chosen by the party’s 180,000 members, who are 97% white; skew older, wealthy and male; and lean to the right of Britain’s political spectrum. Truss does not appear to be hugely popular in polls of the broader public, and she was not the top choice of her party’s lawmakers, but she was the favorite of its members.

The next general election might not be until early 2025; polls give the opposition Labour Party large leads over the Conservatives following the acrimony around Johnson’s fall.

Labour leader Keir Starmer congratulated Truss in a recorded video but added, “The change we need in Britain is not a change at the top of the Tory party,” referring to the Conservative Party by its centuries-old nickname.

Top of Truss’ priorities will be the country’s cost-of-living crisis: skyrocketing bills for food and energy (household electricity and gas bills are set to triple), fears of blackouts this winter and inflation that has sent real-terms wages falling. Millions of people may face the choice between heating their homes or feeding their families, while many small businesses say they will fold unless the government takes action.

Truss has promised to announce her plans on the issue this week. In her acceptance speech, she vowed tax cuts and said: "I will deliver on the energy crisis."

But tackling the crisis is doubly hard because her party is bitterly divided over what to do about it.

Johnson assembled a broad coalition that agreed on one issue — Brexit — said Anand Menon, the director of the U.K. in a Changing Europe think tank. That big tent covers lifelong middle-class Tories in the southern countryside, who may want a small state and lower taxes, to party newcomers from the traditionally Labour-voting north, who generally favor more investment in public services.

“The party is so divided on the only issue that matters to people now, and that’s going to be problematic,” Menon said. “The only issue that matters is the economy.”

Trying to unite those factions is Truss, a political chameleon who, supporters say, has been nimble and pragmatic enough to adapt her views and whom critics decry as opportunistic.

She was born in Oxford to a math professor father and a nurse mother whom she described as “left-wing.” As a student at Oxford University, she supported the centrist Liberal Democrats and advocated such positions as abolishing the monarchy and banning nuclear weapons.

After she switched to the Conservatives, she was elected to Parliament in 2010 following several unsuccessful attempts.

In 2016, she voted to remain in the E.U. in the Brexit referendum. That put her on the liberal — and losing — side of a political and cultural war that has raged ever since. However, she has since switched sides, often displaying the zeal of the convert that seems to have convinced the party faithful.

"She’s loyal, she’s honest, and I’m sure she’ll deliver what she said she would deliver, and I trust her 100%,” said Andrea Andino, 52, sporting an "In Liz we Truss" T-shirt outside the central London conference center where the result was announced.

Tim Bale, a politics professor at Queen Mary University of London, said Truss “wooed” the Conservative grassroots “by telling them what they want to hear — and pretty much only what they want to hear.”

She has tried to burnish those right-wing credentials further by imitating the divisive Thatcher, wearing similar outfits and posing for a photo op in a tank.

Few, if any, pundits regard Truss as a polished orator, and she has become known among critics as overly rehearsed but prone to gaffes. Yet she emerged as the favorite and natural heir to succeed Johnson — still beloved by many on the right even if they accepted it was time for him to go.

In her speech Monday, she paid tribute to Johnson as “my friend."

Johnson quickly repaid the compliment on Twitter, saying Truss "has the right plan to tackle the cost of living crisis, unite our party and continue the great work of uniting and levelling up our country."

Truss had stints as minister for the environment, justice and international trade and most recently as foreign minister, giving her an opportunity to polish her no-nonsense image in dealings over Brexit and Russia’s invasion of Ukraine, where Britain has been a key and valued ally of Kyiv’s defensive fight.

That is unlikely to change with Truss at the helm, although her focus will almost certainly be on the domestic crises greeting her elevation to the top job.
